Fantasy Football Week 15: Top Waiver-Wire Wonder at Each Position

It's getting down to the wire in fantasy football this season, and owners are scuffling for that last piece that will put them over the top.

If your fantasy team has been decimated by injuries or you need a plug-in for Week 15, there are still some waiver-wire wonders who could help you when it matters most.

Let's take a look at the top waiver-wire option at each position for Week 15 (owned in less than 50 percent of ESPN standard leagues as of this writing).

QB: Colin Kaepernick, San Francisco 49ers

Colin Kaepernick not only scored the seventh-most fantasy points among quarterbacks in Week 14, he faces a New England Patriots defense in Week 15 that is allowing 7.8 yards per pass attempt this season (27th in the NFL). That includes giving up 20 passing touchdowns (tied for 20th in the league).

The 49ers are likely going to have to score more than they're accustomed to against the red-hot Patriots. Given New England has also been impressive against the run lately, this may turn out to be a shootout between Kaepernick and Tom Brady (meaning lots of yardage through the air).

Bilal Powell racked up 13 fantasy points in Week 14 as the Jets used a run-heavy approach against the Jacksonville Jaguars.

This is nothing new for Powell, either. The second-year running back has posted a combined four touchdowns in his last four games.

The Jets face the Tennessee Titans in Week 15. The Titans are ranked 13th in yards per carry allowed and they've ceded 12 rushing touchdowns this season, tied for 23rd in the NFL.

WR: Danario Alexander, San Diego Chargers

Danario Alexander not only posted the fourth-most fantasy points among receivers last week, he's been a fantasy gem since Week 10.

Alexander has racked up 496 receiving yards in his past five games while scoring five touchdowns in that span. Yet, he's owned in less than 30 percent of ESPN standard leagues.

He's also facing a middle-of-the-road pass defense in Week 15 going up against the Carolina Panthers. The Panthers rank 16th in the NFL in yards per pass attempt allowed.

TE: Clay Harbor, Philadelphia Eagles

I guess you could say this tight end is your safe harbor for Week 15 (I know, I'm genius).

Taking over for the injured Brent Celek in Week 14 against the Tampa Bay Buccaneers, Clay Harbor caught six balls for 52 yards and a touchdown, registering the third-most points among tight ends in standard leagues.

Celek is out for Week 15, opening up another opportunity for Harbor to shine. The Eagles face a Cincinnati Bengals squad that has been red-hot, but if you're looking for the best waiver-wire add among tight ends this week, you have to go with the 25-year-old.
